Our company file has been having the same issues as mentioned by MainAdmin, and we have 10 user licenses of which we're using only 4 to 5 at any given time. I believe there are frequent instances of database locking where there shouldn't be. One of today's examples is that our dispatch person was working on an invoice using only inventory items, not any billable time line items that would delve into the employee side of things. QuickBooks prevented me from attaching a document to an employee profile until the dispatch person had logged out of QuickBooks.
